I don’t know about you but I don’t need a fancy digital wrench to tell me when bolts are tight. But if you do, then maybe it’s time you go digital with this wrench. This wrench will give you a mathematically precise torque reading.

Just be careful as the wrench “uses the distance from the leverage point to the bolt head to calculate torque, so moving your hand closer to the bolt head will throw off its reading.” How reliable. It can be yours for just $323. Digital is definitely the way to go.

How else are you going t know if a bolt is tight enough?
